|
# Supports: building static/shared, release/debug/etc, can also build html docs
|
|
# and some of the tests.
|
|
# Note that its designed for out-of-tree builds, so it will not pollute your
|
|
# source tree.
|
|
#
|
|
# TODO 1: Finish implementing tests. api tests are working, but the valgrind
|
|
# variants are not flagging problems.
|
|
#
|
|
# TODO 2: There is a check_exports script that would try and incorporate.
|
|
#
|
|
# TODO 3: Consolidate version numbers, currently the version number is written
|
|
# into: * cmake (here) * autotools (the configure) * source code header files.
|
|
# Should not be written directly into header files, autotools/cmake can do
|
|
# that job.
|
|
#
|
|
# Brief intro on how to use cmake:
|
|
# > mkdir build (somewhere - we do out-of-tree builds)
|
|
# > use cmake, ccmake, or cmake-gui to configure the project. for linux, you
|
|
# can only choose one variant: release,debug,etc... and static or shared.
|
|
# >> example:
|
|
# >> cd build
|
|
# >> ccmake -i ../path_to_jansson_dir
|
|
# >> inside, configure your options. press C until there are no lines
|
|
# with * next to them.
|
|
# >> note, I like to configure the 'install' path to ../install, so I get
|
|
# self-contained clean installs I can point other projects to.
|
|
# >> press G to 'generate' the project files.
|
|
# >> make (to build the project)
|
|
# >> make install
|
|
# >> make test (to run the tests, if you enabled them)
|
|
#
|
|
# Brief description on how it works:
|
|
# There is a small heirachy of CMakeLists.txt files which define how the
|
|
# project is built.
|
|
# Header file detection etc is done, and the results are written into config.h
|
|
# and jansson_config.h, which are generated from the corresponding
|
|
# config.h.cmake and jansson_config.h.cmake template files.
|
|
# The generated header files end up in the build directory - not in
|
|
# the source directory.
|
|
# The rest is down to the usual make process.
